An Efficient Sensory System for Intelligent Gas Monitoring Accurate classification and precise quantification of gases/ odors

Abstract

Intelligent gas monitoring system is having its widespread applications. It essentially requires an accurate classification with precise quantification of gases/odors. Although, gas sensor arrays are capable of generating signatures however, mostly these signatures are complex and have subtle information. Therefore, in this paper, an efficient sensory system has been proposed for intelligent gas monitoring. Concept of analysis space transformation has been utilized for accurate classification of gases/ odors. Also, the drawback of data preprocessing in quantification has been illustrated by comparing the quantifier performance for the processed and raw responses. Further, the proposed sensory system has elevated the classification accuracy from 96% to 98.74% along with the quantification accuracy from 17.65% to 94%. © 2020 IEEE.
